The Nautilus Mobia provides a moderate intensity to vigorous intensity cardio workout at an easy walking pace and low impact. The intensity is similar to a stair-stepper or treadmill jogging, but with very low impact like an elliptical machine. The sleek design is welcome for a home workout machine. It has simple controls and a heart rate monitor chest strap. I took a test drive of the Mobia at Nautilus headquarters and I could see the advantages it has for providing a more-intense cardio home workout at a walking pace, using a walking motion.
What is the Mobia?
The Mobia has the low impact of an elliptical machine, but the motion is a simple walk. You don't need any special coordination to use the Mobia.
Mobia has speed settings from 0.5 to 4.0 miles per hour. Runners may scoff at the speeds, but even at the lowest resistance setting I felt a real workout challenge. The Nautilus staff who showed me the machine said they had yet to meet a runner who didn't change their tune once they used the Mobia. This machine can produce a high heart rate workout for the highly fit person as well as a good workout for exercise beginners.
The intensity of the workout is set by both the speed and the resistance setting.
Getting on the Mobia, I felt an immediate challenge both for my legs and immediate engagement of my core abdominal muscles. That was a surprise -- walking usually doesn't call on the core muscles, yet they are critical for good walking posture. With the resistance set a mid-level, my heart rate shot up, yet I was going at a very easy pace. This machine can really deliver a workout.
A Mobia Workout
Mobia is a relatively quiet machine, I had no difficulty hearing the conversation of my hosts while using it. Not only are the treadles quiet, but your feet aren't making any pounding noise on them as the impact is gentle. This is a great feature for a home exercise machine you may want to use while others are sleeping.
Nautilus shows that the Mobia burns more calories at the same speed as level walking or running. This is undoubtedly true, as the workout is all uphill and engages a wide range of muscles. It would be easy to put in a 30 minute Mobia workout that is moderate to high intensity and burns as many calories as level walking outside or on a treadmill 60 minutes at the same pace.
I wouldn't use the Mobia to replace long, slow distance walking training for half marathon or marathon. This is a great machine for a cardio workout, but it can't replace those long days of walking-specific training.
The ability to get a good workout with a fluid, low impact motion at a low speed is great for those who can't walk fast enough to get their heart rate into the moderate zone.

Delivery and Assembly
Bottom LineMy tour of the Mobia impressed me. I could really feel the quality of the cardio workout possible with the Mobia. I loved the fluid motion and that you are simply walking.
The drawbacks would be the pricetag and that this is a new item debuting in November, 2009 without a track record for durability or user reviews.
